Industrial thermocouple sensor
with ceramic protector

"CTPC" range

These industrial thermocouples are used in industrial processes where temperatures are very high.

Thermocouples are protected by one or two ceramic protectors. The choice of the tube material depends on the temperature to be measured and on the working conditions.

Connection to the regulating system is made through a connecting head, generally in aluminium, equiped with a ceramic terminal block or a transmitter.

Maximum working temperature for ceramic protecting tubes in different atmospheres:

_^material	_{^{temperature resistance}}	_{^{resistance to thermal shocks}}	_{^{resistance to mechanical shocks}}	_^protection
_{^{Tight refractory ceramics 610 type}}	_^1600°C	_^-	_^-	_{^{internal or external}}
_{^{Porous refractory ceramics, 530 type}}	_^1200°C	_⁺⁺	_^-	_^external
_{^{Tight pure alumina 710 type}}	_^1600°C	_⁺	_^-	_{^{internal or external}}

The most commonly used thermocouple types are K, N or R, S, B for higher temperatures.

Mechanical data

The thermocouples are generally protected by ceramic beads or tubes.
